摘要
<p>The hydraulic drive comprises a multi-chamber cylinder unit, which has a multi-chamber cylinder (1) and a slidable piston (2), which has a piston rod (3). Each of the active surfaces (19) is impinged with a high pressure or low pressure separately by a valve unit. One of the active surfaces is impinged with the high pressure or the low pressure by a controllable proportional valve unit.</p>
